Outline Panel Firefox

Outline Panel

Sidebar panel showing an outline of the current page with the current section highlighted.

Features & Capabilities

Why make another outline sidebar? Fair question; the extension store is flooded with these things. I made this because I wanted something that:

  • Is designed for everyday use, not for development.
  • Sticks as close as possible to the HTML outline algorithm while remaining usable.
  • Displays inside a true browser sidebar; not a popover mounted to a toolbar button, and not inside the page where the page's scripts and styles can see and accidentally interfere with it.
None of the other options did all three.

Is Outline Panel Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Outline Panel requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ****** ********* ** * ****** ******** ******** ********** * ******* ******* *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Outline Panel is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
